Is 30 a deficient number?

Here we will explain and calculate if 30 is a deficient number and its deficiency if applicable.

30 is a deficient number if the sum of its proper divisors is less than 30.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 5 + 6 + 10 + 15 = 42.

42 is not less than 30. Therefore, 30 is not a deficient number.

The deficiency of 30 is 30 minus the sum of its proper divisors. Thus, the deficiency of 30 is 30 - 42 = No Deficiency
